GAS BURNER.

Application filed June 9, 1921. Serial No. 476,150.

1 0 all whom it may concern:

Be it known that I, Jenn C. TATE, a citizen of the United States, and aresident of the city of Oakland, county of Alameda, State of California,have made a new and useful inventionto wit, Improvements in Gas Burners;and I do hereby declare the following to be a full, clear, concise, andexact description of the same.

This invention relates particularly toan im roved burner. object of thisinventionv is to provide a gas burner wherein either artificial ornatural gas separately or in.combination will burn with a perfectcombustion utilizing all of the heat units therein contained andincidently doing away with the generation of moisture or vapor.

A further object of this invention is to provide a gas burner whereinthe gas and atmospheric air are separately pre-heated prior tocombustion and thus partially decomposed into the elementaryconstituents prior to being intermixed. A further object of thisinvention is to provide a gas burner that is superior in point ofsimplicity, and inexpensiveness of construction, positiveness ofoperation, facility and convenience in use and general efiiciency. Otherobjects and advantages will-appear as this description progresses.

In this specification and the annexed drawings, the invention isillustrated in the form considered to be the best, but it is to beunderstood that the invention is not limited to such form, because itmay be embodied in other forms, and it is also to be understood that inand by the claims following the description, it is desired to cover theinvention in whatsoever form it may be embodied.

In the accompanying one-sheet of drawm s,

igure 1 represents a side elevation through a gas burner constructed inaccordance with my invention partly broken away to show the interiorthereof.

Figure 2 represents an end view of Figure 1.

Figure 3 represents a cross-section taken through Figure 1 on the line3-3.

Experiments have determined that gas burners are not efiicient and donot produce a perfect combustion, in the burning of natural orartificial gas in the natural ,state as contrasted with gas burnersburning natural or artificial gases that have first been pre-heated, soas to raise the temperature or speclfic gravity thereof, where whenmixed with alr, which has likewise been first preheated, the efficiencyis increased and the combustlon more perfect. This invention dealsparticularly with a gas burner Wherein either natural or artificial gasseparately or in combination may be burned efficiently and wlth aperfect combustion, accomplished by pro-heating the gas and also theatmospheric air to a very high temperature be fore they are permitted tomix prior to distribution. Normally where gas or fuel is mixed underordinar tions, it is not conducive to a good combus tion, for the reasonthat the specific gravities of the respective elements differ. Thisinefliciency is overcome by pre-heating the gas and air, raisin" thetemperature and specific gravities of the products to substantially thesame degree whereby a hermonious union of the elements results, forminga volatile mixture. Incidently the preheating of the gas (which is of ahydrocarbon nature) and the air, tends to decompose the same into theconstituent elements and a consequent mixing thereof prevents thehydrogen from passin back into the air in a precipitated form andeliminates the possibility of moisture or vapor accumu, lating in thearea adjacent where the gas is being burned.

In detail the construction illustrated in the drawings, comprises ahollow mixing body generally designated by the numeral 1, which issubstantially oval in cross-section and which at the front end is closedby the wall 2. A portion of the opposite end 3 is opened as at 4providing an intake port. The interior of the mixing chamber ispartially divided by a division or partition member 5, extending fromthe rear wall 3, and above the intake port 4:, to a point adjacent thefront wall 2. Thus air passing through the intake port 4 as indicated bythe arrows into) the chamber 6 would pass around the end of the divisionplate 5 into the space or chamber 9 above the division plate 5.

The exterior of the mixing chamber 1 is provided with a plurality ofprotuberances or projections 7 on its upper face having suitabledischarge ports 8 therein communicating with the interior chamber 9. Afuel supply pipe 10 connects with a gas supply atmospheric condi- (notshown) and is provided with a control valve 11 therein by which thevolume of gas emitted from the pipe 10 may be regulated and controlled.The said pipe 10 is adapted to pass over the upper face. of theprotuberances 7, through a suitable cored depression 12 thereinprovided, bended over the end 23 substantially atright angles theretoand again bended at a right angle. it thus passes through the port atinto the lower division {5 of the mixing chamber, and continuestherethrough into connection with the needle control valve generallydesignated by the numeral 14. removably fixed in the front partition 2ol' the said mixing chamber. The valve member 1-1: comprises an elbow l3comnmnicating with the discharge end of the gas supply pipe where itpasses through the division wall 2. Its opposite end communicates withthe discharge outlet 15 opening into the upper portion 9 of the mixingchamber, said opening 15 being located in a discharge nozzle 16, theexterior of which is threaded into engagement with a hollow threadedbushing 17 removably located in an opening in the front wall 2. Theopposite end of the nozzle 16 is interiorly threaded as at 18 so thatthe threaded body ll: of a needle valve 20 may be placed into adjustableengagement therewith and the tapered point oi said needle valveregulated relative to the discharge opening 15 by the knurled handle 21on. the exposed end of said needle valve. A suitable cap 22 is adaptedto be passed over the exterior of the said nozzle so as to preventtampering with the needle valve.

Although I have shown and described a particular type of gas burner andits construction, I do not wish to be limited thereto as it would beclearly within the purvlew of this invention to modify or re-arrange thesame. This burner operates in the following manner:

Gas admitted through the control valve 11 passes around through the pipeit) and from the opening 15, into the discharge nozzle into the upperdivision 5) of the mixing chamber 1, where it escapes to the atmospherethrough the openings 8 provided in the protuberances 7. When the properamount of gas passes through the openings 8, the operator would igniteor light the same in any suitable manner and control the amount of heataccording to the volume of gas admitted through the regulating valve.ll. The flame of combustion issuing from the openings 8 would impingeagainst the supply pipe and through conduction heat the gas thereincontained. Likewise through conduction, the entire body of the mixingchamber would be. heated to a very high degree. The gas within the tube10 that has been heated and rarefied, moves in the direction of leastresistance toward the discharge opening 15 from whence it escapes intothe interior of the mixing chamber, mixes with atmospheric air and thusissues from the said burner openings 8 in the form of a highlycombustible gas. Atmospheric air passing through the intake port l-isheated by contact with the walls of the mixing chamber so that by thetime it is intermixed with the pro-heated gas, the temperatures of thesame are approximately constant, thus insuring a harmonious union and amore intimate association of the elements and due to a higher specificgravity, a. more perfect combustion is thus obtained.

Where natural and manufactured gases (each oi' which are of differentspecific gravities) are distributed through the same mains, it ofttimeshappens the same do not thoroughly intermix but stratify so that a gasburner regulated to burn the mixed gases either burns with a. roar ornot at all, where the respective gases are introduced separately. Thusby passing gases of different specific gravities into an apparatus suchas l have devised and pre l'iea-ting the same, the temperatures areraised to a. point where the same will readily unite so long as they arekept in a suiliciently heated state and are passed through the burner ata constant pressure.

Although 1 have shown a gas burner that is intended primarily tobe usedin combination with a radiator for heating purposes, it is my intentionto utilize the same principle in burners of different shapes and constructions which may be used either individually as gas burners or incombination as described.

llaving thus described this invention, what 1 claim and desire to secureby Letters Patent is: i
